There is no obvious clinical explanation; indeed, improved hospital hygiene as well as decreased frequencies of some com bacterial infections should have resulted in a decrease in total consumption. This emergent resistance often leads to a need to use newer more expensive antibiotics, in common sleeping pills addition to the costs resulting from therapeutic failures of the initial treatment. In 1991 the most often used antibiotic, phenoxymethylpenicillin, was given in about 20 million defined daily doses (DDD), corresponding to 2.4 DDDs per member of the population per year. Consumption of antibiotics antibiotics in Sweden, 1975 to 1992. Effects of antibiotics on protected specimen clip sampling in ventilator-associated pneumonia.The effects of antibiotic treatment on the results antibiotics of protected specimen brushing (PSB) in ventilator-associated pneumonia were prospectively assessed by performing this procedure before antibiotic treatment, and 12, 24, 48 and 72 h after initiation of antibiotic treatment, in 35 ventilated patients who developed pneumonia during plan-b mechanical ventilation. This data confirms that prior antibiotic treatment, even after only a few hours of activity, significantly decreases the sensitivity of protected brush specimen; this effect appears to be particularly marked among the species involved in early ventilator associated pneumonia. Overconsumption pain relief was most marked for oral antibiotics. The introduction of 'diagnosis-related groups' (DRGs) for reimbursement of hospitals for in-patient care is likely to result in the development of antibiotic use in 'intensive sick bay care' as has occurred in the US. Within 12 h of the initiation of effective antibiotic treatment a rapid, significant decrease in the numbers of organisms isolated, their individual concentrations and the percentage of positive PSB results were observed. More serious is the marked misuse of tetracyclines (12 million DDDs in 1991) and macrolides (5.3 million DDDs in 1991), with which adverse reactions are more com and where the high consumption has led to increasing frequencies of resistance among com bacterial pathogens. Pharmacoeconomic and clinical ing official statistics for the consumption of antibiotics in Sweden during the period 1975 to 1991, the pharmacoeconomic consequences were analysed. From a pharmacoeconomic viewpoint, this overconsumption is acceptable because the drug has a low price and causes a minimum of severe adverse reactions. Certain bacterial species (Streptococcus pneumoniae, Haemophilus influenzee) appeared to be more vulnerable to antibiotics than others (Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumanni). The number of micro-organisms isolated, their concentration (colony-forming units (cfu) mL(-1)), and the number of cases with a positive PSB (> or 10(3) cfu x mL(-1)) were evaluated. An increase of more than 25% in Swedish consumption of antibiotics during the study period was found. Of the parenteral antibiotics, the cephalosporins, particularly cefuroxime, dominate in Sweden.
